Techniques for data retention upon detection of an event in an implantable medical device
First Claim
1. An implantable medical device comprising:
- (A) a first monitoring element that receives a first signal set associated with a brain activity;
(B) a second monitoring element that receives a second signal set associated with a second type of physiologic activity;
(C) a processing component capable of detecting a possible occurrence of a physiological event based on the first or second signal set; and
(D) a memory component that stores at least a portion of the first signal set and at least a portion of the second signal sets upon detection of the possible physiological event.

Abstract
Methods and apparatus for storing data records associated with a medical monitoring event in a data structure. Upon detection of a possible occurrence of a physiological event by one group of monitoring elements, an implanted device records data received from another group of monitoring elements. The implanted device obtains and stores the data in the data record in a first data structure that is age-based. Before an oldest data record is lost, the oldest data record may be stored in a second data structure that is priority index-based. The priority index may be determined by a severity level and may be further determined by associated factors. The implanted device may organize, off-load, report, and/or display a plurality of data records based on an associated priority index. Additionally, the implanted device may select a subset or composite of physiologic channels from the available physiologic channels based on a selection criterion.

17. A method for retaining physiologic data in an implantable medical device comprising:
-
(A) receiving a first signal set associated with a physiologic condition;
(B) receiving a second signal set;
(C) detecting a possible occurrence of a neurological event based on at least the first signal set;
(D) storing in a first data structure a plurality of data records relating to at least the second signal set upon detection of the possible neurological event, each data record representing information about an associated event; and
(E) storing in a second data structure at least a portion of a first data record from the first data structure if an associated priority index of the first data record exceeds a threshold criterion. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
